Sensored/Sensorless Brushless Speed Controller
for Car or Truck
Thank you for your purchasing this Brushless Electronic Speed Controller (ESC). This electronic
speed controller is specifically designed for operating Sensored/Sensorless brushless motors. High
power systems for RC models can be very dangerous and we strongly suggest that you read this
manual carefully. We have no control over the correct use, installation, application or maintenance
of these products, thus no liability shall be assumed nor accepted for any damages, losses or costs
resulting from the use of this item. Any claims arising from the operating, failure or malfunction, etc.
will be denied. We assume no liability for personal injury, property damage or consequential
damages resulting from our product or our workmanship. As far as is legally permitted, the
obligation for compensation is limited to the invoice amount or product in question.
Features:

Enhanced throttle response, excellent acceleration, strong brakes and throttle linearity

Advanced software interface for setting up and firmware updates.

Uses LCD or LED program card for adjustments.

Multiple protection features: Low voltage cut-off protection, over-heat protection and
throttle signal loss protection

Compatible with brushless sensored/sensorless motors.
Setup
Please check all connections carefully and make sure they are connected properly.
Sensored Mode:
When using a Sensored Brushless motor, the Blue motor wire A, the Yellow motor wire B and the
Orange motor wire C of the ESC must be connected with the Sensored motor wire A,B,C
respectively. It is necessary to connect the Sensor wire to the "Sensor" socket on the ESC. It is
important to not alter the order of motor wires when using with a sensored motor.
Sensorless Mode:
When using a Sensorless Brushless motor, the Blue motor wire A, the Yellow motor wire B and the
Orange motor wire C of the ESC can be connected with the motor wires in any order. If the motor
runs in the opposite direction, please swap any two wire connections.

LEDs:
Sensored/sensorless function
When the Power wires on the ESC are connected with the battery pack, the ESC can automatically
identify the motor type (Sensored/Sensorless) via indicated LEDs. Sensored cable must be
removed for ESC to operate in sensorless mode.

Throttle Range Calibration
The ESC must be calibrated when used for the first time, and any time a new radio/receiver is
used.
For the first time using transmitter or changing the transmitter you must set up Throttle Range
Calibration.
1. Switch off the ESC, then connect ESC to battery and turn on the transmitter; set the EPA/ATV
(travel) value of the throttle channel to the maximum setting in both directions (can be 100%,
125%, 150% etc. depending on radio).
NOTE: Some radios must have throttle channel set to REV (e.g. Futaba, Flysky).
NOTE: If your radio is equipped with ABS braking it must be disabled for calibration.
2. Hold the "set" button down and turn on ESC while still holding the "set" button. After about 4
seconds the LED will turn SOLID BLUE. Release the "set" button, and immediately apply full
throttle and hold it. The LED will FLASH RED and then turn SOLID RED. Motor will beep.
3. Immediately apply full brake (do not stop at neutral). The LED will FLASH BLUE and then turn
SOLID BLUE. Motor will beep.
4. Return throttle to neutral position. RED and BLUE LEDs will flash, and then turn solid and then
off. Motor will beep. Throttle has been calibrated.
5. Turn the ESC back ON. The ESC is now ready to use.

Sensored/Sensorless brushless ESC general information
1. Cutoff Voltage
Automatically detects number of cells
ESC automatically detects number of cells in battery pack. You can program the cut-off voltage as
an individual cell voltage. For example, if you set cut-off to a 3.2v. cell, a 2S LiPo pack will cut-off at
a total pack voltage of 6.4v. Cut-off can be programmed via program card or PC software.
When using NiMH or NiCd batteries you do not need to set a cutoff voltage to protect the batteries.
If you are using more than 6-cell NiMH or NiCd batteries, you must adjust the cutoff voltage. For
example if you are using an 8-cell pack of NiMH batteries, you would use a cutoff of 5.6V volts (8 x
